The incidence of migration of the disc fragment in LDH varies from 35% to 72%. The high up migrated disc herniation into MacNab’s hidden zone remains technical challenge. We provide a technical note of seldomly performed full endoscopic translaminar approach with its potential indications. A 52 years male patient presented with low back pain with left lower limb radiculopathy for 2 months. Visual analogue scale for back and leg was 2 and 8, respectively. MRI examination revealed high up migrated disc herniation with collapsed disc space at L4-5. Dynamic radiograph was not showing any instability. Based on the preoperative surgical planning working cannula was docked over left L4 lamina perpendicular to horizontal plane. With the help of 3.5 mm endoscopic burr translaminar keyhole was drilled in a concentric manner. The distance between lateral margin of pars and keyhole was intermediately inspected for preservation of adequate bone in pars interarticularis. Though the translaminar key hole subluxated tip of SAP, up-migrated disc fragment was removed. The VAS score of leg reduced significantly from 8 to 2 in immediate postoperative period. At the end of 6 months follow up period patients leg symptoms completely improved with minimal back pain. We measured the width of remaining pars postoperatively and found to be 5 mm. The full endoscopic translaminar approach is valid alternative approach for the high up migrated HNP.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124470941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The widespread accessibility of advanced technologies and imaging modalities has led to an increase in the popularity of minimally invasive (MIS) techniques in cranial and spinal pathologies. Methods: The study was conducted at a university hospital in Bogotá, Colombia. All data were obtained from the database of the hospital’s Neurosurgery Department. After institutional review board approval, the medical records of patients who underwent MIS posterior fossa decompression for CM1 were retrospectively reviewed.Results: Thirty-six patients underwent posterior fossa decompression through a minimally invasive approach during the study period. Nineteen patients met the inclusion criteria and were included in the data analysis. The patients’ chief complaints were headache (78.9%) and neck pain (57.9%). The average surgical time was 158.2 ± 50.5 minutes, with no significant difference in timing among different specialists. The most common postoperative complications were associated with dura closure, including 6 patients with pseudomeningocele and one patient with cerebrospinal fluid leak.Conclusion: Different surgical techniques have been proposed for posterior fossa decompression of CM1. In the present study, we favor a minimally invasive approach to the craniocervical junction to preserve as much of the normal anatomy as possible and avoid alterations in spinal biomechanics.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131173515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Foraminotomy was performed using the biportal endoscopic technique, with the surgeon standing on the opposite side and making skin incisions on the same side of the foramen stenosis. After widening of the V-point and exposing the nerve root using a high-speed drill, we used a curved osteotome to undercut the facet joint from inside the foramen to complete the nerve root decompression. Results: The study followed patients for an average of 15.5 months and found significant improvements in the visual analog scale for arm pain, from 7.3 ± 2.2 to 0.9 ± 0.7 (P < 0.005), and the Neck Disability Index, from 54.6 ± 16.9 to 14.6 ± 12.6 (P < 0.005). Almost all patients (94.4%) had good or excellent results. Hospitalization lasted an average of 3.2 days and postoperative magnetic resonance imaging showed successful neural decompression. Complications were minimal, with only two cases of asymptomatic root abrasions and one case of transient neuralgia. One patient required re-operation due to incomplete decompression.Conclusion: BEPCF is a safe and effective surgical technique for treating cervical radiculopathy. The surgeon can achieve good neural decompression and preserve the facet joint using the inside-out approach in an ergonomic setting.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129340147","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MISS has gained popularity due to its reduced pain, minimal scarring, and shorter recovery times compared to traditional open surgery. Endoscopic surgery, the core of many MISS procedures, offers several advantages, such as reduced blood loss, minimal tissue damage, shorter hospital stays, and enhanced visualization. However, it is important to emphasize the need for sufficient experience in endoscopic surgery and the adoption of more delicate techniques when addressing cervical and thoracic spine disorders, as more serious complications can occur in these regions than in the lumbar spine. Various endoscopic techniques, including anterior cervical discectomy, posterior cervical foraminotomy, thoracic discectomy, and thoracic decompression, have been successfully employed to treat cervical and thoracic spine disorders. As the field of spinal surgery continues to advance, the use of endoscopic techniques in MISS is expected to become more widespread, benefiting patients and contributing to a more efficient and cost-effective healthcare system.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"492 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133922922","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interlaminar approach is commonly described as thoracic endoscopic unilateral laminotomy for bilateral decompression (TE-ULBD), which is typically indicated for pathologies such as ossified ligamentum flavum and other posteriorly based compressive pathologies. TE-ULBD decompresses the central and lateral recesses of the thoracic spinal canal. Both the outside-in (over the top of ligamentum flavum) and inside-out (under the ligamentum flavum) approaches can decompress the thoracic spinal canal through the uniportal interlaminar endoscopic route.Methods: A retrospective clinical cohort evaluation of patients who underwent TE-ULBD was performed from January 2018 to December 2021 Results: A cohort of 50 cases of TE-ULBD with a mean age of 65 years old were evaluated. The complication rate was 5.4% and the reoperation rate was 2%. Statistically significant mean VAS improvements were found at 1 week, 6 months, and the final follow-up, with changes of 3.95 ± 1.49, 4.95 ± 1.7, and 5.2 ± 1.8 points, respectively. Likewise, the mean Oswestry Disability Index improvements at 1 week, 3 months, and the final follow-up were 33.8 ± 9.05, 40.12 ± 10.38, and 41.92 ± 11.26, respectively (p < 0.001). Significant improvements were found in the cross-sectional area of the spinal canal in the upper endplate, mid-disc, and lower endplate (57.62 ± 50.6, 89.86 ± 55.93, and 64.93 ± 60.91 mm2, respectively; p < 0.001).

To address these issues, unilateral biportal endoscopy (UBE) techniques for thoracic laminectomy have been developed and published, demonstrating various advantages over conventional thoracic laminectomy with satisfactory clinical results. In comparison to conventional thoracic laminectomy, the UBE decompression technique with the unilateral approach and bilateral decompression (ULBD) appears to be safe and effective for treating thoracic ossified ligamentum flavum (OLF) or thoracic spinal stenosis. Thoracic ULBD by UBE preserves the paraspinal muscle and ligament that would otherwise be resected during the conventional posterior approach, and it has the added benefit of reducing back pain and muscle atrophy. This manuscript covers the technical aspects of UBE implementation using thoracic ULBD in patients with thoracic OLF or thoracic spinal stenosis, the indications and benefits of this procedure, and tips for preventing complications. With a review of previously published articles on thoracic laminectomy by UBE, we also summarize whether the procedure is safe and can prevent cord injuries.","PeriodicalId":405058,"journal":{"name":"Journal of Minimally Invasive Spine Surgery and Technique","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130755042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: We searched PubMed/MEDLINE to identify articles on the prevalence of degenerative diseases with compression of the spinal cord in the cervical and thoracic spine. The levels of evidence were classified according to the NASS 2005 method. We selected articles containing information on the prevalence of degenerative cervical and thoracic diseases.Results: We identified 358 articles. Thirty-eight met our criteria, with evidence ranging from levels I to V. The prevalence of asymptomatic spinal cord compression lesions was found to be relatively high in elderly people with underlying conditions. Non-traumatic spinal cord injuries are caused by various degenerative diseases involving spinal cord compression, such as cervical myelopathy, ossification of the posterior longitudinal ligament, and ossification of the ligamentum flavum, and are observed in more than 50% of patients with lesions in Japan and the United States, more than 30% in Europe, and more than 20% in Australia.
